ing to upload thewrong firm-
ware. The upload process is
simply stopped in its tracks.
We finally did it all cor-
rectly; the update process
proceeded without any prob-
lems and was completed in
a reasonable 15 minutes, a
little bit faster than the 20
minutes specifiedbyRohde&
Schwarz.
You shouldwithout a doubt
allow for some time for this
process to complete and, if
you‘re using a laptop for this
update, it should alsobe con-
nected to a power source to
avoid any possible surprises
with the laptop‘s battery.
After restarting the R&S
EFL210, itwas instantly ready
togo. All of thenew functions
could now be checked out.
Higher
Waterfall

Speed
An immediately noticeable
improvement was the speed
of the waterfall diagram in
leakage mode. Now it scrolls
smoothly at a rate of 10 lines
per second which is on aver-
age four to five times faster.

Sensitivity
It wasn‘t only the speed
that was improved in Leak-
agemode, but the sensitivity
of the analyzer as well. Now
3 μV/m - 9.5 dBμV/m can be
differentiated where before
it was only 11 μV/m - 20.8
dBμV/m. Finer details can
now be recognized in the HF
spectrum.
AUTOCONFIG
Function for the
Waterfall Diagram
Leakage mode now has a
new AUTO CONFIG function
that automatically adapts
the reference level and the
level range to the signal. This
function can be programmed
into either the F1 or F2 func-
tion buttons so that the user
can adapt the waterfall dia-
gram to the signal level at
any time.
NoiseLevel
AlwaysVisible
Along with the AUTO CON-
FIG function there‘s also an
additional improvement: the
noise level is now always
displayed in the spectrum
so that even very weak sig-
nals canbe recognizedat any
time.
Automatic
Leakage
SearchFunction
A really one-of-a-kind and
especially useful function
is the new Leakage Search
function. This allows for the
automatic search for leakage
in the LTE band. The ana-
lyzer determines if there is
any typical cable TV leakage
in the LTE band and displays
on the screen a correspond-
ingmessage and at the same
time produces a signal tone.

The EXT.AMP function can
